Answer 1

I remember seeing a crash like this and reading about a bug with 4.0.x in particular where removing a hardware layer in an AnimationListener (onAnimationEnd()) would cause this sort of crash. The solution was to post the layer transition as a Runnable. For example:

@Override
public void onAnimationEnd (Animation animation) {
    //This will cause a crash
    setLayerType(LAYER_TYPE_NONE, null);
}

@Override
public void onAnimationEnd (Animation animation) {
    //This will work successfully
    post(new Runnable() {
        @Override
        public void run () {
            setLayerType(LAYER_TYPE_NONE, null);
        }
    }
}
